8: Problem 2 (10 points) Find the point on the line 1z + 3y-1-0 which is closest to the point (-2,-6). Of course you can solve this problem in the same way you solved similar problems at the beginning of this semester, but it should be a lot easier now. using derivatives. Write down an expression for (the square of) the distance, differentiate, set to zero, and solve the resulting equation to get x
